Seems there’s virtually no connectivity available while riding the Metro subway. Verizon is the only cellular carrier with cell towers in the subway, so those of us who rely on alternate carriers like AT&T are just out of luck while underground. In addition, the Metro system does not offer Wi-Fi, so there’s no Internet access. Since all mobile cell and Internet communications involve the good old air waves, I say there’s virtual radio silence while riding the D.C. area subway. Oh, well, maybe there are actually times when it’s good to disconnect and get away from it all…
